Resilient plug and a waterproof connector

摘要

A waterproof connector (10) has a terminal fitting (30) connected with an end of a wire (60). A resilient plug (40) is mounted on the end of the wire (60) and has a main body (42) held onto the wire (60) by the terminal fitting (30). A housing (20) has a cavity (21) into which the terminal fitting (30) and the resilient plug (40) are inserted. Outer lips (46) project on the outer circumferential surface of the main body (42) and are held resiliently in close contact with the inner circumferential surface of the cavity (21). Auxiliary lips (47) with a smaller projecting amount than the outer lips (46) also project on the outer circumferential surface of the main body (42). The outer lips (46) and the auxiliary lips (47) are arranged to lean against each other if the wire (60) is shaken.
